Setup a Linux Server

Setting up a Linux server depends on the service that you wish to use with the server. Before setting up the server, make sure that your computer meets the system requirements. It requires at least 512 MB of RAM, 2 GHz processor, a network card, and a 500 MB hard drive. For detailed information regarding the Linux server setup, go through the steps mentioned below.

Ubuntu Server Setup:

• Ensure that you have updated the system components like kernel, package manager, and other installed packages. 
• If you have not updated, open the Terminal app and type the ‘sudo apt update’ command.
• Type the ‘sudo apt list –upgradable’ command to list the packages upgrade.
• Next, start the system upgrade process using the ‘sudo apt upgrade’ command.
• To remove the downloaded deb packages and app caches, enter the ‘sudo apt autoremove’ and ‘sudo apt clean’ commands.
• To create a new account in Ubuntu, enter the ‘sudo adduser ubuntu_user’ command.
• Enter the ‘sudo usermod -a -G sudo ubuntu_user’ command to grant administrative privileges to the user account.
• To install the package, enter the ‘sudo apt install package_name’ command.
• If necessary, update the package using the ‘su – ubuntu_user’ and ‘sudo apt update’ commands.
• Next, configure the system host and set up the public key with authentication.
• Make sure to install the key to a remote SSH server and secure the SSH daemon by changing the default port.
